基于稀疏环结构PET的蒙特卡洛模拟
Monte Carlo simulation of PET based on sparse ring structure
摘要
Abstract
The technique of positron emission tomography(PET)utilizes radionuclides to label specific elements.Based on the NEMA NU 2-2012 standard,using Biograph Vision PET/CT as a model,the Monte Carlo method was used to study the effects of different sparse ring gaps on PET scattering fraction and sensitivity.The research result indicated that the simulated values of sparse ring PET scattering fraction and sensitivity in this paper were close to their experimental values.Therefore,the sparse ring PET simulation in this paper was reliable.关键词
